BACKGROUND Field

The present disclosure relates generally to ridable vehicles and, more specifically, to a ridable scooter with a rotational connection.

Description of the Related Art

Riding on vehicles such as scooters or skateboards is a popular recreational activity. Scooters have become popular among many age groups and there are many different scooter variations and designs. Some scooters generally have at least two wheels and some type of steering mechanism. Some scooter designs include four or more wheels.

SUMMARY

Some scooters require a user to use his or her feet to push on the riding surface (e.g., the ground) to propel the scooter. It can be desirable that some scooters may be propelled without the use of a power unit (e.g., a motor). For example, it can be desirable for a scooter to be propelled through a twisting motion without requiring the user to use his or her feet to push on the riding surface and propel the scooter.

An aspect of one or more embodiments involves the realization that it is desirable to allow a user to ride on a scooter and move the scooter without the use of a motor or the user pushing off the riding surface. Therefore, the current arrangements in the prior art for ridable scooters are unsuitable and/or could be improved and/or made more desirable.

The systems, methods, and devices described herein have innovative aspects, no single one of which is indispensable or solely responsible for their desirable attributes. Without limiting the scope of the claims, some of the advantageous features of certain embodiments will now be summarized.

In some aspects, the frame structure further includes a first rotation member and a second rotation member and the steering mechanism is connected to the second rotation member that is rotatable with respect to the first rotation member. In some aspects, an application of a lateral force on the steering mechanism results in tilting of the steering mechanism relative to the frame structure and the steering mechanism is biased to return to an initial position when the application of lateral force is removed. In some aspects, the pivot axis of each of the first and second rear wheels is inclined with respect to the first and second foot placement platforms. In some aspects, the scooter device further includes a brake assembly configured to selectively apply a braking force to the front wheel. In some aspects, the steering assembly further comprises a steering support member coupled between the steering shaft and the frame structure. In some aspects, the frame structure further includes a longitudinally-disposed support member, and the steering support member is connected to the longitudinally-disposed support member. In some aspects, the longitudinally-disposed support member comprises a first member and a second member and the first member is configured to rotate with respect to the second member.

DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS

Reference will now be made in detail to various embodiments of the present technology, which relates to various personal mobility devices, such as scooters. Although certain specific embodiments of the present technology are described, the present technology is not limited to these embodiments. On the contrary, these described embodiments are merely illustrative of the present technology, and the present technology is intended to also cover alternatives, modifications, and equivalents. Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present technology. However, it will be recognized by one of ordinary skill in the art that embodiments may be practiced without these specific details. In some instances, well known methods, procedures, compounds, compositions and mechanisms have not been described in detail as not to unnecessarily obscure aspects of embodiments of the present technology.

For the purposes of this disclosure, embodiments of personal mobility vehicles will be referred to as “scooters”, but it will be understood by those with ordinary skill in the art that the present disclosure extends beyond the specifically disclosed embodiments and references to scooters to other alternative embodiments and/or uses of the invention and modifications and equivalents thereof. In particular, while the present vehicles and related methods have been described in the context of particularly preferred embodiments as it relates to scooters, the skilled artisan will appreciate, in view of the present disclosure, that certain advantages, features and aspects of the systems and methods may be realized in a variety of other applications, including personal mobility vehicles other than scooters and/or scooters with different arrangements of front and rear wheels.

In a preferred embodiment, a scooter device 10 may include a frame structure 20 that is coupled to a steering mechanism 50. In some embodiments, the frame structure 20 is connected with at least two rear wheels 22, 32. The frame structure 20 is connected to the steering mechanism 50 with a steering mechanism support member 25. The frame structure 20 may include a joint structure 40 from which legs 24 and 34 extend. In the embodiment of FIG. 1, a longitudinally disposed support is configured as multiple rotation members 18, 19 or other structure that connects the steering mechanism support member 25 and the legs 24, 34. The first and second rotation members 18, 19 are preferably configured such that the second rotation member 19 rotates with respect to the first rotation member 18, as will be discussed in greater detail below. In some embodiments, the second rotation member 19 may fit or slide within an end of the first rotation member 18. For example, as shown, the first and second rotation members 18, 19 can be generally coaxially aligned. Support member 25 may be non-movably coupled to steering mechanism 50 (shown in FIGS. 1-2) or movably coupled through a pivot or otherwise coupled.

The steering mechanism 50 includes a steering shaft 54 that is coupled to a front wheel 12 on one end and ascends to a handlebar 53 at its other end. In some embodiments, the steering shaft 54 is generally parallel to a vertical axis. The steering shaft may include multiple (telescoping or otherwise configured) sections and a height adjustment mechanism. The handlebar 53 may include two handgrip portions 56, 57 that the user may use to steer and control the scooter 10. As shown, the handlebar 53 may include one or more hand brakes 58, 59 that the user may actuate to brake the scooter. The hand brakes 58, 59 can be operably connected (e.g., via a cable) with a brake assembly (not shown) that is configured to engage to brake the scooter. For example, the brake assembly can be configured to engage with one of the wheels.

The scooter device 10 can include a location for the user to sit or stand. For example, the scooter device 10 may have a plurality of user platforms 42, 52 that are coupled to the legs 24, 34. As shown, in some embodiments, the platforms 42, 52 of FIGS. 1-2 extend substantially over the rear wheels 22, 32. The platforms 42, 52 provide surface areas on which a user can place their feet to ride on the scooter and/or perform stunts with the scooter.

In some embodiments, the rear wheels 22, 32 are caster wheels (and thus can also be called “rear swivel caster wheels”). In some embodiments, the rear wheels 22, 32 each comprise a wheel, fork, and shaft. The two rear wheels 22, 32 are preferably mounted in a forward tilted caster arrangement. This arrangement achieves a wheel that is capable of turning via rotation about its mounting shaft, yet which self-returns to the line of direction at which it is mounted. In some embodiments, the rear wheels 22, 32 are each tilted, relative to vertical, at least about: 5°, 10°, 15°, 20°, 25°, or otherwise.

The rear wheels 22, 32 may have a centering mechanism, which is configured to bias the rear wheels to a neutral (e.g., forward) steering position. For example, a spring action device may be mounted between the rear wheels 22, 32 and some portion of the user support platforms 42, 52 of the scooter. This can provide rotational resistance to the rear wheels 22, 32 relative to the platforms 42, 52. In certain embodiments, centering of the rear wheels 22, 32 may be provided by a biasing mechanism (e.g., torsion spring arrangement, such as a helical torsion spring). In these embodiments, the spring provides resistance to pivoting or turning of the fork about its turning axis. The biasing mechanism may also provide rotational resistance and a biasing force on the rear wheels to return the rear wheels to their neutral steering position when the scooter is being propelled by the user in a forward direction. Additional details regarding such centering wheels and/or biasing mechanisms can be found, for example, in U.S. Pat. No. 7,195,259, which is hereby incorporated by reference in its entirety.

As discussed above, the support member 25 connects the steering mechanism 50 to the frame structure 20. In some embodiments, the support member 25 may be fixedly coupled to the frame structure 20. For example the support member 25 may be welded or bolted to the frame structure 20.

In certain implementations, the support member 25 may be dynamically connected to the frame structure 20. For example, the support member 25 can connect with the second rotation member 19, which can be configured to move (e.g., rotate) relative to the first rotation member 18 of the frame structure 20. In some embodiments, the first and/or second rotation member 18, 19 includes a biased cam or the like that permits movement of the support member 25 with respect to the legs 24, 34 of the frame structure 20. In some variants, some or all of the support member 25 comprises a generally rigid, yet flexible, material with elastic properties, such as fiberglass, flexible metal, polyurethane or the like. The generally rigid, yet flexible, support member can permit the steering mechanism 25 to move relative to the legs 24, 34, which can permit a user to lean the steering mechanism 50 into a curve.

As shown in FIG. 3, the second rotation member 19 preferably permits movement (e.g., side-to-side movement) of the support member 25 and the steering mechanism 50 in response to a displacement force applied by the user, such as a generally lateral force that the user applies via the handgrip portions 56, 57. In some embodiments, the second rotation member 19 is configured to return to a rest position (e.g., an initial position) in the absence of the displacement force. In some embodiments, in the rest position, the steering shaft 54 is generally parallel to a vertical axis, such as is shown in FIGS. 1 and 2.

In certain implementations, since the support member 25 is coupled to the steering mechanism 50 and to the second rotation member 19 (which is configured to move relative to the first rotation member 18 of the frame structure 20), the steering mechanism 50 can be moved (e.g., tilted) relative to the legs 24, 34 and the user platforms 42, 52. This can permit a user to adjust the steering mechanism 50, such as to lean the steering mechanism 50 into a turn, etc. In certain embodiments, the steering mechanism 50 is configured to tilt, from a vertical position and in a first direction (e.g., right), at least about: 30°, 40°, 50°, 60°, 75°, or otherwise. In various embodiments, the steering mechanism 50 is configured to tilt, from a vertical position and in a second direction (e.g., right), at least about: 30°, 40°, 50°, 60°, 75°, or otherwise. In some implementations, the steering mechanism 50 tilts independently of frame structure 20. For example, tilting of the steering mechanism 50 up to at least about 30° from vertical does not substantially move the frame structure 20. In some variants, tilting of the steering mechanism 50 up to at least about 40° from vertical does not result in either of rear wheels 22, 32 being raised off of the riding surface (e.g., ground).

As shown in FIGS. 1 and 2, rear wheels 22, 32 may be mounted below the foot or user platforms 42, 52. The rear wheels 22, 32 are preferably mounted to the platforms 42, 52 such that, in response to the user leaning the steering mechanism 50 to its right side (with respect to the advancing direction of the scooter), the rear wheels 22, 32 will roll to the right so that the user can turn the scooter device 10 to the right. Alternatively, in response to the user leaning the steering mechanism 50 to its left side (with respect to the advancing direction of the scooter), the rear wheels 22, 32 will roll to the left with respect to the advancing direction so that the user can turn to the left.

In some embodiments, to propel the scooter 10, a user shifts his or her weight from side to side on the platforms 42, 52 of the frame structure 20. This can apply a force to the frame structure 20 that results in the frame structure 20 moving relative to the steering mechanism 50. For example, such movement of the frame structure 20 can cause the steering mechanism 50 to rotate relative to the frame structure 20. As the user moves the frame structure 20 side to side due to the application of force on the platforms 42, 52, the rear wheels 22, 32 will make rolling angles with respect to the advancing direction or direction of travel. As a result, the user can propel the scooter 10 forward by twisting his or her body side to side without moving his feet from the platforms 42, 52. Alternatively, or in addition to the propulsion method discussed above, the user may use his feet to propel the scooter 10 by, for example, pushing against the ground.

In some embodiments, the scooter 10 may include a power mechanism 55, as shown in FIG. 1. The power mechanism 55 may be configured to provide power to front wheel 12 to propel the scooter without the user needing to push with his or her feet and/or without needing to move the frame structure side to side as described above. In some embodiments, the power mechanism 55 includes an electric motor 23 that drives the front wheel 12 using a belt. In many instances, the electric motor is a 250 W variable speed electric motor, though any of a variety of electric motors can be used. The power mechanism 55 preferably includes a battery that may be used to power the electric motor 23.

As shown, the legs 24, 34 can be connected by the first rotation portion 18. In some embodiments, the legs 24, 34 are connected by only the first rotation portion 18. In some embodiments, as shown in FIG. 2, additional support members, such as shaft 21 may run between the legs 24, 34 to provide additional stability to the scooter 10.
